Kiosk maintenance: a daily, weekly and monthly care plan

Wipe the screen and card reader every day with the cleaner your kiosk's maker names, sprayed on a cloth first. Check the card reader for tampering before each shift. Keep spare receipt paper at hand, run updates after close, and write every check in a log so a warranty claim has a record behind it.

This guide covers upkeep once the kiosk is running. For what staff do when a guest gets stuck, see kiosk staff help. For choosing a kiosk, see the kiosk buyer's guide.

What do kiosk makers say about cleaning?

All four makers below clean with a cloth or wipe and ask you to keep moisture out of openings. The cleaners they name differ.

Maker	Cleaner it names	What it warns against
Toast	70% isopropyl alcohol on a microfiber cloth; wipe the whole device, back included, and let it air dry	Alcohol above 70 percent, methyl or ethyl alcohol, ammonia, abrasives, 409 cleaner
Clover	Water first, then 70% to 90% isopropyl alcohol on a soft, lint-free cloth, with the device off and unplugged	Liquid near seams, buttons and card areas (use a dry cloth there), abrasive cleaners, solvents
Elo (I-Series 4.0 manual)	Wet wipes or a damp cloth with the excess squeezed out; power down first if you can	Alcohol above 70%, undiluted bleach, ammonia
Apple (a compatible iPad used with Square Stand and Kiosk Lite)	A 70 percent isopropyl alcohol wipe, a 75 percent ethyl alcohol wipe or Clorox Disinfecting Wipes	Bleach, hydrogen peroxide, moisture in any opening

Use the instructions for the exact model, including its screen, card reader and stand; one maker's cleaner is not a rule for every device. The Apple row applies to an iPad used with Stand and Lite, not the standalone Square Kiosk. Even Elo models differ: its EloPOS manual says to use window or glass cleaner on the touchscreen and not alcohol.

Clover asks for touched surfaces to be cleaned at least once a day. Elo suggests powering down or making sure the software can take false touches while you wipe, so clean before opening or after close.

How do you check a card reader for tampering?

A kiosk's card reader sits in the open, often out of a cashier's sight. The PCI Security Standards Council's skimming prevention guide for merchants (September 2014) tells merchants to keep a list of all devices and to inspect them on a set routine, which "could be once a day or at the beginning of each shift." It also says to photograph each terminal front and back, labels and serial numbers included, and to compare new photos with old ones. It warns against unannounced service visits or upgrades you have not checked with your provider.

Clover's tamper help page lists signs to look for. A short version for the opening check:

1. The reader is in its usual place and the serial number matches your photo.
2. No cuts, broken seals, peeling labels or new scratches, most of all around the seams.
3. No overlay or loose wire in or near the chip slot or PIN area.
4. The same number of cables, in the same colors, as last time.
5. A card goes in and out with the usual feel.

Clover devices also detect some tampering on their own. When that happens, PIN payments stop and the owner or an admin requests a replacement. Clover says a replacement is free within the warranty period, though shipping and handling fees may apply. If you find something wrong on any system, stop taking cards on that kiosk, send guests to the register and call your processor.

How do you keep the receipt printer running?

First find out where your kiosk prints. Clover Kiosk ships with a receipt paper roll in the box, per Clover's kiosk setup guide. Square's Kiosk Lite setup guide routes tickets through printers connected to counter devices; Lite does not connect directly to receipt printers. The standalone Kiosk FAQ also says kitchen printers currently need Square POS hardware. Confirm the actual device and printer route before choosing the maintenance steps.

Toast's TP200 printer guide gives these steps for the TP200. Use your own printer's manual for other models:

• Paper: the TP200 takes 80 mm thermal paper (3 1/8" × 230'). Toast does not sell paper. To test a roll, scratch the print side with a fingernail: thermal paper leaves a black mark.
• Jams: if paper stops or will not exit, open the cover, replace an empty roll, clear debris from the cutter and print head, and re-seat the paper.
• Faded print: clean the print head and the rubber platen roller with a cotton swab and rubbing alcohol.
• First fix for most faults: unplug power and Ethernet, wait 30 seconds, plug back in and print again.

When should software updates happen?

Schedule maintenance after close or at a quiet hour. Square's Kiosk Lite troubleshooting guide asks you to avoid peak hours. It lists updating the POS app, signing out and back in, and restarting the hardware. Its Lite restart path is to hold two fingers on the screen, then choose Hardware, Connect and manage, and Restart. Use the instructions for the standalone Kiosk if you have that model; do not apply an iPad app procedure to it.

Updates also end. Toast's Product Lifetime Policy says Toast supports its products for three years after the hardware warranty ends, with support that may include automatic software, firmware and security updates. After that a device may stop getting them. Write the end date in your log.

What do the warranties cover, as printed?

Vendor	Warranty term	Conditions worth knowing
Square Stand with Kiosk Lite	Stand: one-year limited warranty	Compatible iPad is bought separately; check its own cover
Square Kiosk, standalone	Two-year limited warranty, per the current Kiosk product page	Confirm covered parts, return terms and your order before buying
Toast (US)	12 months from shipment for handheld devices, 24 months for other Toast products	Excludes abuse, accident and installation not done by a Toast representative; return the faulty unit within 30 days of an advance replacement shipping, or pay for the replacement plus shipping
Clover (bought hardware)	A limited warranty covering manufacturer defects for one year, per Clover's pricing FAQ	Subscriptions include Clover's Equipment Protection Program instead
Elo	Three years for Windows I-Series; two years for Android I-Series	Tell Elo in writing within 30 days of finding a fault; you ship it at your own cost; liquid intrusion is excluded

Elo's liquid clause is one more reason to spray the cloth first.

What should you keep in the spares box?

• Two or more rolls of the right paper for each printer.
• Card reader cleaning cards, which Toast names for cleaning inside a reader.
• Microfiber cloths and the cleaner your maker names.
• A spare power cord and Ethernet cable for each kiosk.
• The original boxes. Elo asks for returns in the original carton or an equal one, Toast in proper packaging, and Clover sends a tampered unit back in the replacement's box.
• A printed copy of each serial number, warranty end date and support phone number.

What goes on the daily, weekly and monthly list?

When	Task
Before opening	Tamper check on each card reader; start a test order to see the menu load, then cancel it; paper check
After close	Wipe screen, reader and stand with the maker's cleaner; log any fault from the day
Weekly	Install pending updates and restart; clean print heads if receipts look faded; count spare paper
Monthly	Compare each reader with its photos; check stand bolts and cables; test the outage plan; review the log and warranty dates

For the outage test, see kiosk payments and cash, which covers what each POS kiosk does offline.

What should the log sheet record?

Keep one sheet per kiosk by the register, or one shared sheet with a kiosk column.

Date and time	Kiosk and serial	Task or fault	What you found	Action taken	Initials

The PCI guide suggests rotating the person who does device checks, so the same initials should not fill every row. Log downtime minutes too; the kiosk pilot checklist uses them as a pass rule.

Maple's voice ordering kiosk is in early access with a small number of restaurants. Maple supplies the kiosk, every screen has a staff-help button, and the restaurant can turn Maple off on any kiosk with one tap. Ask Maple's team for the cleaning and repair steps for the unit it supplies, and add them to your log.
